To alt wkom 'llt may concern:

Be it known that we, WILLIAM J SCHULTZ and HERBERT, GERDING, citizens of the p United States, .and residents of Cincinnati,- 1n the countyof Hamilton and State of Ohio,

have invented a certain new and useful Improvement in Loose-Leaf Books, ofwhich the following isa description. t 7 Our 'nvention rel" tee to an improvement 10 in loose leaf books, and-Which vare known as f ring-books, and consists in providing a suit- .able-cover with a metallic late possessing the requisite resiliency, w ose ed es are curled u onitself to receive the shou ders of 15.8, pair 0 hinged plates, each of said plates beingprovided with se ments of rings, and

: independently. mounted be pulled apart or opened to ermit of p the insertion or withdrawal of te leaves, which have been previously erforated at pointsregistering with the hooks or rings. The ob ect of our invention is to prov de a device of the descriptionset forth, which will be simple in construction a i may be readily Q bound into book form, and at the same time possess the requisit strength; the construction being such s to permit of the rings or hooksbeing opened to a considerable extent and thus overcome the objection made to some of the devices now on the market.

Inthe' drawings :Figure 1 is aperspective view of. our improved book without the leaves, showing the eaf-retaining means in a closed condition: Fig. 2 is a perspective view of the retaining late with a portion of one ofthe curled or ent sides broken away to more clearly show its construction: Fig. 3 is a cross-sectional view taken adjacent the ring-segments, and with portions of the cover removed, the ring-segments being shown opened out to their ful est extent.

Like letters of reference indicate identical parts in the respective figures. 3 v A are covers whichrnay be made integral, of suitablematerial, with the portion to form the back having less stiffness, so as to ermit the covers to be folded upon themse ves intobookform, thus having the covers to also form" the back and hinged portion ofathe book, as clearly seen in Fi s. 1 and 3. y

B is a'metallic'lplate whlch is of a length corres ondi'ng'wit inten' ed to make, and has its sides rolled or curled-iiponvitself as seen at a. The late B preferably made with the extende ends 6' so that they may the size of the book it is which extend beyond the curled or bent edges'for a purpose to be hereinafter set forth. This plate B is also preferably provided withopenings c at suitable intervals, so that a strip' of binding d may take lengthwise across the plate B and be glued thereon, thev openings 0 permitting the glue on the strip to set or adhere to the back or cover A as at the points (1 (see Fig. 3'), thus firmly securing plate B in place. In addition to the strip the edges of the binding or cover may be lapped over the points or ends I) of the plate ,thereby giving a neater finish to the book, and at the same time'reinforcing strip (1, and insuring against any displaces ment of the plate B.

C, C, are metallic plateswhose adjacent edges are cut out at intervals as seen at a, so 'as to permit portions of the one plate to take into thecut-out ortion of the other, as clearly shown: and theSe portions are curled or bent upon themselves as seen at f (see Figs. 1 and 3) to permit of the insertion of a pin 9 to form a hinge. These platesC, C are ent downwardly and outwardly so as to form the shoulders 72-, permitting the outwardly extending part to take beneath the curled or bent edges a of the plate B, and the shoulders to butt against the'edge the curlededge, as clearly seen in Figs. jandS. The distance across the plates from shpulder to shoulder is preferably slightly greater, when the plates are in the sanie horizontal plane, than the distance between the curled or bent edges (1 of the plate B against which the shoulders take, so that when theplates C, C are inserted in place, plate B will be slightly spread or sprun out of its normal condition, thusholding. t e hinged lates J, C under a tension, by reason of t e resiliency of plate B which is made concaved a shown.

,Each of the plates C, C is provided with a segment of a ring D, D, of which there may be any number. These segments are-firmly secured to the plates (1, (J in any suitable manner, as by soldering or otherwise and the one segment D is preferably proyided with a notch as at j'to receive the point'k of the segment D, forming a tight connection between the segments which insures against accidental displacement of the segments. 4

'When it is desired to use the device. the user grasps the opposite segments'of the kit - occasion requlres, and in case it is desired to of the retaining plate B, so as to bring the outer edges of the hook or ring plates (l, (Q slightly past the dead centci", and below the'horizonta-l plane of the hinge, when the resiliency or action of the plate B will be to draw the outer edges of the plate t, down and toward each other, as seen in Fig. 3. in order that the action of plate I) may not be exerted too far and bring the shoulders together underneath the hinged plates, and thus practically release the hinged or ring plates C, we secure the rings or segments D, D, on the plates in such a. manner that they will engage the curled edges of plate B when the rings or segment-s are opened, as can. be seen in Figs. 1 and 3t g The leaves, which have been previously perforated at points registering with the rings, are then in-- s eited over one side or set of segments of the rings, when the s gments'of the rings may be againbrou ht together by either forcing the free ends of the segn'icnts toward each other, or by pressing on the plates t, C at the lunged portion, which will bring the outward or shouldered ends of the plates (f, (7 u ward and past the dead center or slightl above the horizontal plane of the hinge, as shown in Fig. 1.

It will be seen that leaves may be readily inserted or withdrawn from time to time as remove the leaves with the hook or ringplates, by reason of breakage, or for any other reason, the same may be done by simply drawing the hook or ring plates 0, (1 out. at either end of the retaining plate B, which can more easily be done when the plates and rings are closed as shown in Fig. 1.

It will be seen from the fore oing description and drawings, that our (cvice is constructedmvith few parts, is simple in construction, and can readily be assembled and put into b form, thus overcoming serious objections that have been encountered 'ith some of the devices now in use.

What we claim as our invention and wish to secure by Letters Patent is 1. A loose leaf book comprising a cover, a spring-plate adapted 'to be secured to said cover, the side edges of said plate curled upward or bent toward itself, a pair of plates hinged-together,-said plates each provided with an angular shoulder adapted" to take against the curled or bent edge of the springplate, ring-segments secured to each of said hinged plates, and adapted to engage the curled edges of the spring-plate, and thereby limit the action of said plate on the hinged plates when the ring-segments are separated.

2." A loose leaf book comprising a cover, a spring-plate secured to said cover, and having its edges curled or bent toward itself, a pair of plates hinged together at their one edge,,the other edge of said plates being bent dmvi'iward and outward to form shoulders, said shoulders taking against the curled edges of the spring-plate, each of said hinged plates being provided with segments of a ring, the segments on the one ada )ted to register with the segments on the other and form rin s, said segments adapted to butt against tic curled edges of the spring-plate when they are opened outwardly.

3. A loose leaf book comprising a cover, a spring-plate secured to said cover, said spring-plate having its sides bent or curled toward itself, and its ends extending beyond the bent or curled portion thereof, a pair of hinged plates provided with shoulders against, which the curled or bent up sides of the spring-plate are adapted to press, said hinged plates being provided with. segments of rings. the segments on the one plate registcrii'ig with the segments on the other, and so sc cured on the hinged plates as to take against the curled edg s of the spring-platc, and limit thereby the motion of the hinged plates.

4, A loose leaf book comprising a, cover, a spring- 'ilate secured on said cover, said plate having its side edges curled toward itself, a pair of plates provided with angular shoulders against which the curled edges of the springplate take, the adjacent edges of said. plateslming curled upon themselves and away in places to receive portions of each other, a pin t 1g through the curled portions of said plates and forming a hinge, segn'ients of ringsccurcd to each of said hinged plates and registering with each other, and so secured as to take against the curled edges of the spring-plate when the segments are separated to limit the action of the hinged plates.

5. A loose leaf book comprising a cover, a spring-plate secured on said cover and having its sides curled upward and toward itself, the ends of said plate extending beyond the curled sides thereof, a pair of plates whose adjacent edges have cut away portions to permit them to interlock, the outward sides of said plates being bent downward and outs ward to form shoulders which are ad aptcd to take against the curled up edges of the springplate and be held under tension, segments of rings adapted to register with each other secured on the interlocked plates so as to take against the curled edges of the spring plate and limit its action on the interlocked plates.

6. A loose leaf book comprising a cover, a spring-plate adapted to receive a binding strip to secure it to said cover, the sides of said plate being curled upward and toward itself, a pair of plates Whose adjacent edges have cut away portions to permit them to interlock, said edges .being curled or bent upon themselves to receive a pin and form a hinge, the hinged plates being bent downwardly and outwardly to form angular shoulders adapted to take against. the curled edges cut of the spring-plate, the distance between the.

shoulders of the hinged plates being slightly greater than the distance between the edges of the spring-plate, so that the position of the hinged plates will be maintained by the ac- .tion of the spring-plate, segments of rings secured on said hinged plates at points to bring them against the curled edges of the spring-plate when the' segments are separated and thereby limit-the motion of the hinged plates.

7. A loose leaf book comprising a cover, a spring-plate secured onsaideover andadapted to receive a binding strip, the sides of said plate being curled upward and toward itself,

, a pair of plates having notches on their adjacent sides to permit them to interlock, said edges being curled upon themselves to receive a pin to form a hinge, the hinged plates being provided with angular shoulders adapt- .ed'to press against the curled up edges of the spring-plate whereby the position of the hinged plates is maintained, said hinged plates being provided with segments of rings. at such points as to have-them be ar upon the curled edges of the spring-plate when the segments are opened outward, thereby limiting the motion of the hi' ed plates.

8. In a temporary binder, a set of mating prongs, a spring men ila'er loosely carrying said prongs and having; points of contact the edges of the plate, the inner ends of the two members intcrnieshing and each member having an addltlonal point of contact with the plate, whereby the (nicning IIHWO mentis limited.
